Yes, you did say...but after the fact. Then to me, it sounded like an excuse.

So, I guess we didn't have good communication.

Can the tuning be corrected?

So the #'s were high by 11 hp before right? freddie was at 259 which would mean now he would be at 248 if he had the same setup and dyno'ed his car there again recently.

So what you are trying to say is that he lost 2whp by adding a bigger turbo, bigger (supposedly better) tmic, silicone hoses, and ecutek which is better than the unichip by far?

Please explain that.

I already did if you read my last message. Dyno differences are in quantified in %, not a fixed hp number. The bigger the number, the bigger the difference. Double the hp number, double the delta.

Ok, so the dyno was off by about 6% or so. So that means with freddies old setup on the new dyno calibrations he would be at 242whp. The larger topmount, turbo, and tuning only did a 4whp difference? That sucks. It has to be either the products or the tuning.

All I was told is that a pe1818 spools better so it gets boost faster allowing you to get into your power band sooner. And if I saw saw 50hp at first, then put on the pe1818 I would see at least 60 hp......so thats what I was expecting.

Not trying to piss anyone off...just repeating what I was told.

People that have put on this turbo w/out tuning even noticed a BIG difference.

With CA 91 gas, we are OCTANE LIMITED. That means, no matter what modifications we have, we will only be able to make a certain amount without running into detonation. You cannot play the addition game with respect to additional mods. Things like intercoolers, turbos, etc,. will have a much more profound change on output consistency, torque curve shape, etc,. than absolute peak hp numbers which will be bottlenecked at a certain point.

In the case of a WRX, the MOST we've been able to safely make on pump gas, on our dyno, is 250-260wheel hp. In fact, anything over 250 wheel hp is considered a resounding success. On 93 octane, we usually see an increase of about 10-15 wheel hp at Stage 2-like levels. On 100+ octane, the sky is pretty much the limit as long as there is enough airflow supplied by the induction system (turbo, ic, etc,.)

Even our Stage 3 car, on pump gas, has only been tested to make 260 wheel hp. On 100 octane race gas, however, it makes 368 wheel hp since we are able to run appropriate boost, fuel and ignition values. Values that simply aren't safe when running 91 octane.

Cheers,
shiv
When are you high HP guys going to accept the fact that gas in CA SUCKS!!!

If you want to make that magica HP number move out of state where REAL gas can be found.

Considering that my WRX is not a racecar (yet) and for the most part has to deal with daily driving, I am happy that I can make a SAFE 260 whp thank's to Shiv.

If you don't like it, go to someone else, and have them tune your car to the ragged edge and beyond. That is something that Vishnu will not do...

Well, if I saw 260 this last time I wouldn't be complaining so much....please start reading from the BEGINNING

maybe they should get a base line before the ECUTEK tuning.... So, they see the difference.....if any.

IIRC, the PE 1818 has the exhaust housing from the VF-30 so it shouldn't spool faster than a VF-30 and the blower of a VF-22 so it should make a slightly better peak than a VF-30. The only thing I know it spools better than is a PE 1820.

so, this brings MORE questions to mind!!!!
I don't know much about the turbo, just what I was told by a few people. It was supposed to be better than the vf30/34 so that's why I got it....to add a little more umph. I was also told it is better in the mid to high end range than the vf34.

Also, when you spin the blades of the pe1818....it spins A LOT LONGER then on the vf34.

thanks for the info

Give him a free re-tune! It's only fair. You admitted to tuning it with the mindset that it was a different turbo. That's not his fault it's yours.

I'm not trying to speak for anyone but I don't think shiv just puts in a pre-program, I think what he does is run your setup on your car till it pings and then he backs off. He then does several back-to-back runs to ensure that you get the same curve despite heatsoak this ensures both a consistant tune and a safe one.

This means the car is tuned for his turbo - I personally think he probably should have gotten a few more horsies, but he didn't (there must have been a sign of detonation or lean condition). I don't think that is necessarily anyones fault.

Good Luck.

I for one, can sympathyze with Freddie. All that money spent, and a decrease in HP. I would be torqued too. I also feel that blaming the problem on a "Bad batch of 91 octane" is a sorry excuse. The PE1818 is the second best IHI bolt on that you can buy. It is far better than the VF34. That's why it is so much blingage!

Freddie know's the dilemmas that I am facing right now as well. Hopefully my kinks can be worked out.

I think that a courtesy re-tune is in order in this situation. Does anybody agree with me?

Poor Fred (Barney!!! Willma!!!)

Yeah, I lowered the back about .5 inch and got an alignment. I had the chance to make a fun run up Page Mill Road. The wagon handles great. That road puts the suspensoin to the test because of all the bumps and ruts in the road. The road was a little wet and had some gravel/dirt on some turns. I found myself drifting through the switch-backs . I checked my tires after the run and found that I was rolling on the edges a bit. I'll increase the tire psi and see how it handles then. I think I may need to increase the sway bars a bit the allow the rear to come around.

I'm goinf to Reno in the Am and will get to play in some snow maybe.

OK, I was re-reading this mess...and saw this.....so I remembered that I was talking to Alex (imrezer) a while ago and he said, when he first did his mods to his wrx....he pulled 300whp on "pump gas" on Shivs dyno.

So, what does "pump gas" include? We can go to 76 and get 100 octain at the pump.

Maybe Alex was mistaken....or meant 100??

well, I talked to Alex today, and he said his 300whp on Shivs dyno was on 91 octane

CupertinoSteve, said today that he got his 261. on 91 octane.....with a little bit of ping @6500 RPM. intersting....I heard he only got that on "race gas".....I forget who told me though
